Awesome! I hope you have a kick ass time with your camera! And I would still highly recommend that lens. Its not as much about zoom as close-quarters shooting.
Post up some photographs as soon as you start playing with your camera.
What I did was go through the manual, A to Z. It helps you learn all the functions and you take photos as you go along. Its quite useful. Let us know how you progress and what kind of photographs are you looking to take.
camera is not a car, where your first buy should be second hand.
keep a budget of $2000. invest in good. there are tons of example on the net, compare the results. and before buying, make sure you test it.
else, gidsa has provided you with enough of good information
For a beginner on the Nikon side I’d suggest atleast a D5100. Its reasonably priced with excellent features and leaves room to buy a good lense (I’m assuming $1500 budget).
For lenses you defintely need wide angle but for portraits etc a good telephoto (over 100mm) is a must. Most of these new cameras come with 18-55mm VR lens as a kit which is a really good start.
